Directing to another page as part of script

magic-chef

Is it possible to have a user directed to another page after a script is run.

For example a user registers or updates his info. If the update is successful I want to send them to a specific home page for members only.

I have used headers for other situations but they cannot be used if there has already been output.

you can call a javaScript function and in that function use a top.location.replace("link") and that should do what you want to do...

HTH

I really don't know how to do that.

suppose the link is "membersindex.php"

How would I do it?

magic-chef

function gotopage(link)
{
top.location.replace("link");
}

I placed this in the script section of the page (in the header)

when I try to call this in PHP:

gotopage(index.php);

I get the following error:

Fatal error: Call to undefined function: gotopage() in /.....l/register.php on line 39

Can JS functions be called directly in PHP?

How can I call the function?

PHP can't actually call a client-side JavaScript function (somebody correct me if I'm wrong), so you need to include the JavaScript in the output HTML. You actually don't even need to define a JS function for this purpose. Just echo the JS command to the page and it will be executed by the browser:

$link = 'membersindex.php';
echo "<script type='text/javascript'><!--
top.location.replace('$link');
// -->
</script>";

Just out of curiosity, if you are providing an automatic redirect upon successfully executing a PHP script to do whatever, then why would you have sent output to the browser already? It seems that if the user submits a form to update their info, then have PHP do a header() redirect to the appropriate page once the info has been successfully changed...

To answer your last question the test is found in a function that is called as part of a form being created.

Also, the echo string did not work for me. I replaced the $link with the correct page name.

BTW, here is the code:

$link='index.php';
echo "<script type='text/javascript'></script>";

There is a variable test which preceeds this line. I have an echo set up and the test is successful. Yet, no page redirect.

u can still use headers if you use ob_start() and ob-flush. read it up in the manual

http://ca3.php.net/manual/en/function.ob-flush.php

Actually, I wouldn't have normally used top.location.replace(). I just posted it that way to keep in line with what the prior posts were saying. I usually use top.location.href='$link'

See if that works...

First for zeb:

This is the current code. It doesnot work either.

$link='index.php';
echo "<script type='text/javascript'></script>";

Kevin,

WHen would I make the obj_start() call? Before any output? Or could it be used anytime for couple of lines and then obj_flush() to produce the page? The man was not clear to me on this.

Call ob_start before you output anything.

Then call:

ob_end_clean(); // clear anything that is in the buffer
header('Location: wherever.php');
exit; // no need to do anything else

And to fix the javascript code above:

$link='index.php';

echo "<script language=\"javascript\">window.location.href = '$link';</script>";
